I have looked at related Qs on Stack.
I am trying to sort my query to display month in ascending order. A similar post on Stack said that I must indicate "ASC", but this doesn't work for me. I have written an Order By. I cannot figure out why it is not working.
SELECT DATENAME( MONTH,(Submission.SubmissionDate)) AS [Date]
FROM Submission
GROUP BY DATENAME( MONTH,(Submission.SubmissionDate)) ORDER BY [Date] ASC;
This is the output:
Month
August
February
September
Note: this is just a part of my query, I didnt think it would necessary to show the rest, which relates to other attributes from my table (Not month related)
Edit: This is my Entire Query: (The Initial One)
SELECT DATENAME( MONTH,(Submission.SubmissionDate)) AS [Date],
SUM( CASE WHEN Submission.Status='Under review' THEN 1 ELSE 0 END) [Under_Review],
SUM( CASE WHEN Submission.Status='Accepted' THEN 1 ELSE 0 END) [Accepted],
SUM( CASE WHEN Submission.Status='Rejected' THEN 1 ELSE 0 END) [Rejected],
SUM( CASE WHEN Submission.Status='In print' THEN 1 ELSE 0 END) [In_print],
SUM( CASE WHEN Submission.Status='Published' THEN 1 ELSE 0 END) [Published]
FROM Submission INNER JOIN ((Faculty INNER JOIN School ON Faculty.FacultyID = School.[FacultyID]) INNER JOIN (Researcher INNER JOIN ResearcherSubmission ON Researcher.ResearcherID = ResearcherSubmission.ResearcherID) ON School.SchoolID = Researcher.SchoolID) ON Submission.SubmissionID = ResearcherSubmission.SubmissionID
GROUP BY DATENAME( MONTH,(Submission.SubmissionDate))
ORDER BY DATENAME( MONTH,(Submission.SubmissionDate));
SELECT DATENAME( MONTH, Submission.SubmissionDate) AS [Date]
FROM Submission
ORDER BY datepart(mm,Submission.SubmissionDate)
You don't need a group by (for the query shown). Also, when you order by month name it would return results in the alphabetical order of month name. You should not use previously defined aliases in the where,order by having and group by clauses.
Edit: The problem is with the join conditions. You should correct them as per the comments in line.
SELECT DATENAME( MONTH,(Submission.SubmissionDate)) AS [Date],
SUM( CASE WHEN Submission.Status='Under review' THEN 1 ELSE 0 END) [Under_Review],
SUM( CASE WHEN Submission.Status='Accepted' THEN 1 ELSE 0 END) [Accepted],
SUM( CASE WHEN Submission.Status='Rejected' THEN 1 ELSE 0 END) [Rejected],
SUM( CASE WHEN Submission.Status='In print' THEN 1 ELSE 0 END) [In_print],
SUM( CASE WHEN Submission.Status='Published' THEN 1 ELSE 0 END) [Published]
FROM Faculty
INNER JOIN School ON Faculty.FacultyID = School.[FacultyID]
INNER JOIN Researcher ON School.SchoolID = Researcher.SchoolID
INNER JOIN ResearcherSubmission ON Researcher.ResearcherID = ResearcherSubmission.ResearcherID
INNER JOIN SUBMISSION ON Submission.SubmissionID = ResearcherSubmission.SubmissionID
GROUP BY DATENAME( MONTH,(Submission.SubmissionDate))
ORDER BY DATEPART( MONTH,(Submission.SubmissionDate))
A simple option is to add MONTH(Submission.SubmissionDate) to your group by clause, and order by that as well:
SELECT DATENAME( MONTH,(Submission.SubmissionDate)) AS [Date]
FROM Submission
GROUP BY MONTH(Submission.SubmissionDate), DATENAME( MONTH,(Submission.SubmissionDate))
ORDER BY MONTH(Submission.SubmissionDate)
This will work for your real query as well.
You can use MIN() or MAX():
SELECT DATENAME(MONTH,(Submission.SubmissionDate)) AS [Date]
FROM Submission
GROUP BY DATENAME(MONTH,(Submission.SubmissionDate))
ORDER BY MIN([Date]) ASC;
This chooses an arbitrary date from each group and orders by that.
By the way, you probably should care about the year as well as the month. If so:
SELECT YEAR(s.SubmissionDate), DATENAME(MONTH, s.SubmissionDate) AS [Date]
FROM Submission s
GROUP BY YEAR(s.SubmissionDate), DATENAME(MONTH, s.SubmissionDate)
ORDER BY MIN([Date]) ASC;

I would like to exclude the categories sub_tag1, sub_tag2 and sub_tag3 of tag from the TAG_SALES_by_month but the rest whatever i mentioned in the where condition need to be included in the count. I couldn't achieve the desired result.can anyone help me to achieve the same, which would be very much appreciated.
select o.tag,
o.SOME, o.THING, o.ILIKE, o.date, c.THE, c.MOST,
date_part(month, o.date) as Month,
date_part(day, o.date) as day,
count(o.id) over (partition by day, CUST_Id) as SALE_NO,
count(o.id) over (partition by Month, CUST_Id) as SALE_NO_by_month,
count(case when (tag <> 'sub_tag1' AND tag <> 'sub_tag2' AND tag <> 'sub_tag3') then o.id else 0 END) over (partition by Month, CUST_Id) as TAG_SALES_by_month,
c.id as CUST_Id
from order_info o
left join config c on o.SOME = c.SOME
where date >= '05/01/2021' AND tag in ('sub_tag1', 'sub_tag2', 'sub_tag3', 'sub_tag4', 'sub_tag5',
'sub_tag6') AND ILIKE = 'JACK'
group by o.tag, o.SOME, o.THING, o.ILIKE, o.date, c.THE, c.MOST, CUST_Id, o.id
order by date
Per the comments, the issue here is the that COUNT will return 1 for any value, it counts existence vs not existence of a value/row.
So COUNT(CASE WHEN... ELSE 0...) will still count 1 on the ELSE condition, since 0 is a value that exists.
The solution is to use ELSE NULL or omit the ELSE clause which will default to NULL, because NULL will not be counted.
I have Table1 and I need a query to populate Table2:
Problem here is with Date column. I want to know the process of location/partner combination per day. Main issue here is that I can't pick DateCreated and make it as default date since it doesn't necessarily cover whole date range, like in this example where it doesn't have 2015-01-07 and 2015-01-09. Same case with other dates.
So, my idea is to first select dates from some table which contains needed date range and then perform calculation for each day/location/partner combination from cte but in that case I can't figure out how to make a join for LocationId and PartnerId.
Columns:
Date - CreatedItems - number of created items where Table1.DateCreated = Table2.Date
DeliveredItems - number of delivered items where Table1.DateDateOut = Table2.Date
CycleTime - number of days delivered item was in the location (DateOut - DateIn + 1)
I started with something like this but it's very like that I completely missed the point with it:
with d as
(
select date from DimDate
where date between DATEADD(DAY, -365, getdate()) and getdate()
),
cr as -- created items
(
select
DateCreated,
LocationId,
PartnerId,
CreatedItems = count(*)
from Table1
where DateCreated is not null
group by DateCreated,
LocationId,
PartnerId
),
del as -- delivered items
(
select
DateOut,
LocationId,
ParnerId,
DeliveredItems = count(*),
CycleTime = DATEDIFF(Day, DateOut, DateIn)
from Table1
where DateOut is not null
and Datein is not null
group by DateOut,
LocationId,
PartnerId
)
select
d.Date
from d
LEFT OUTER JOIN cr on cr.DateCreated = d.Date -- MISSING JOIN PER LocationId and PartnerId
LEFT OUTER JOIN del on del.DateCompleted = d.Date -- MISSING JOIN PER LocationId and PartnerId
with range(days) as (
select 0 union all select 1 union all select 2 union all
select 3 union all select 4 union all select 5 union all
select 6 /* extend as necessary */
)
select dateadd(day, r.days, t.DateCreated) as "Date", locationId, PartnerId,
sum(
case
when dateadd(day, r.days, t.DateCreated) = t.DateCreated
then 1 else 0
end) as CreatedItems,
sum(
case
when dateadd(day, r.days, t.DateCreated) = t.Dateout
then 1 else 0
end) as DeliveredItems,
sum(
case
when dateadd(day, r.days, t.DateCreated) = t.Dateout
then datediff(days, t.DateIn, t.DateOut) + 1 else 0
end) as CycleTime
from
<yourtable> as t
inner join range as r
on r.days between 0 and datediff(day, t.DateCreated, t.DateOut)
group by dateadd(day, r.days, t.DateCreated), LocationId, PartnerId;
If you only want the end dates (rather than all the dates in between) this is probably a better approach:
with range(dt) as (
select distinct DateCreated from T union
select distinct DateOut from T
)
select r.dt as "Date", locationId, PartnerId,
sum(
case
when r.dt = t.DateCreated
then 1 else 0
end) as CreatedItems,
sum(
case
when r.dt = t.Dateout
then 1 else 0
end) as DeliveredItems,
sum(
case
when r.dt = t.Dateout
then datediff(days, t.DateIn, t.DateOut) + 1 else 0
end) as CycleTime
from
<yourtable> as t
inner join range as r
on r.dt in (t.DateCreated, t.DateOut)
group by r.dt, LocationId, PartnerId;
If to specify WHERE clause? Something Like that:
WHERE cr.LocationId = del.LocationId AND
cr.PartnerId = del.PartnerId
I want to get the highest value in my query
Select SUM(CASE WHEN Day='Monday' THEN 1 END) AS'Total Monday',
SUM(CASE WHEN Day='Tuesday' THEN 1 END) AS'Total Tuesday'
FROM tbl_sched
WHERE teacherID='2014279384'
The Output would be TotalMonday ='1' and TotalTuesday ='2'
I need to get the highest value from the outputs which in this case is TotalTuesday=2
select max(daycnt) from
(Select SUM(CASE WHEN Day='Monday' THEN 1 END) AS daycnt
from tbl_sched WHERE teacherID='2014279384'
union all
Select SUM(CASE WHEN Day='Tuesday' THEN 1 END) AS daycnt
from tbl_sched WHERE teacherID='2014279384')
If you need the max between many columns:
Something interesting in SQLServer 2008 and above
SELECT (SELECT Max(v)
FROM (VALUES ([Total Monday]), ([Total Tuesday]), ...) AS value(v)) as [MaxDate]
From
(
Select SUM(CASE WHEN Day='Monday' THEN 1 END) AS'Total Monday',
SUM(CASE WHEN Day='Tuesday' THEN 1 END) AS'Total Tuesday'
..........
FROM tbl_sched
WHERE teacherID='2014279384'
)a
Another option:
SELECT Case When [Total Monday] > [Total Tuesday] then [Total Monday] else [Total Tuesday] End as maxvalue
FROM
(
Select SUM(CASE WHEN Day='Monday' THEN 1 END) AS'Total Monday',
SUM(CASE WHEN Day='Tuesday' THEN 1 END) AS'Total Tuesday'
FROM tbl_sched
WHERE teacherID='2014279384'
)a
I'd say the query below is better in terms of performance and highlights the intention better, because basically we are just GROUPing by days and COUNTing the groups, we don't need CASE's or SUM's (in which case SQL Server will have to go over all the records of the selected teacher).
SELECT TOP 1 Day, COUNT(*) AS Total
FROM tbl_sched
WHERE teacherID='2014279384'
AND Day IN ('Monday','Tuesday')
GROUP BY Day
ORDER BY Total DESC
You can just group by Day, sort by COUNT(*) DESC and get the top count:
SELECT TOP (1)
TotalCount = COUNT(*)
FROM
dbo.tbl_sched
WHERE
teacherID = '2014279384'
GROUP BY
Day
ORDER BY
TotalCount DESC
;
You can also include Day into the output to return the day that had the topmost result.
You can achieve this by using Max Function
Select MAX(SUM(CASE WHEN Day='Monday' THEN 1 END)) AS 'Total Monday',
MAX(SUM(CASE WHEN Day='Tuesday' THEN 1 END)) AS 'Total Tuesday'
FROM tbl_sched
WHERE teacherID='2014279384'
I have a query that groups by the field description. (There are 9 total descriptions.) I need to somehow combine 3 of these descriptions into one group, giving me a total of 7 descriptions. I'm brand new to sql querying, so I'm fairly lost on anything beyond JOINS and WHERE clauses so far. I appreciate the help.
SELECT serviceclass.description, DATEPART(Year, meterread.readdate) AS Year, DATEPART(Month, meterread.readdate) AS Month, SUM(meterread.consumption)
AS Consumption, COUNT(DISTINCT accountservice.account_id) AS Locations
FROM accountservice INNER JOIN
serviceclass ON accountservice.serviceclass_id = serviceclass.serviceclass_id INNER JOIN
meterread ON accountservice.accountservice_id = meterread.accountservice_id
WHERE (#Year = DATEPART(Year, meterread.readdate))
GROUP BY serviceclass.description, DATEPART(Year, meterread.readdate), DATEPART(Month,meterread.readdate)
ORDER BY Year, Month
You can achieve this by using a CASE statement.
replace serviceclass.desription in your SELECT and GROUP BY clauses with
CASE
WHEN serviceclass.description IN ('Desc1','Desc2','Desc3')
THEN 'JointDescription'
ELSE serviceclass.description
END
and also update the Desc 1 ~ 3 with your three description and updated the joint description to what you want it to be.
RESULT:
SELECT CASE
WHEN serviceclass.description IN ('Desc1','Desc2','Desc3')
THEN 'JointDescription'
ELSE serviceclass.description
END as description,
DATEPART(Year, meterread.readdate) AS Year,
DATEPART(Month, meterread.readdate) AS Month,
SUM(meterread.consumption) AS Consumption,
COUNT(DISTINCT accountservice.account_id) AS Locations
FROM accountservice
INNER JOIN serviceclass ON accountservice.serviceclass_id = serviceclass.serviceclass_id
INNER JOIN meterread ON accountservice.accountservice_id = meterread.accountservice_id
WHERE (#Year = DATEPART(Year, meterread.readdate))
GROUP BY CASE
WHEN serviceclass.description IN ('Desc1','Desc2','Desc3')
THEN 'JointDescription'
ELSE serviceclass.description
END,
DATEPART(Year, meterread.readdate),
DATEPART(Month,meterread.readdate)
ORDER BY Year, Month
You would typically do this with a case statement that would go in both the select and group by statements. Something like:
select (case when serviceclass.description = 'A' then 'B'
else serviceclass.description
end) as description
. . . -- fill in with query here
group by (case when serviceclass.description = 'A' then 'B'
else serviceclass.description
end), . . . -- rest of query goes here
I have the following SQL query
SELECT
[Date],
DATENAME(dw,[Date]) AS Day,
SUM(CASE WHEN ChargeCode IN (SELECT ChargeCode FROM tblChargeCodes WHERE Chargeable = 1) THEN Units ELSE 0 END) ChargeableTotal,
SUM(CASE WHEN ChargeCode IN (SELECT ChargeCode FROM tblChargeCodes WHERE Chargeable = 0) THEN Units ELSE 0 END) NotChargeableTotal,
SUM(Units) AS TotalUnits
FROM
tblTimesheetEntries
WHERE
UserID = 'PJW'
AND Date >= '2013-01-01'
GROUP BY
[Date]
ORDER BY
[Date] DESC;
But I get the error message:
Cannot perform an aggregate function on an expression containing an aggregate or a subquery.
Because I am using sub queries in the Case Else Summation.
How can I revise my query to get 2 x Sums of [Units] one for Chargeable = true, and one for Chargeable = false, even though the Chargeable field is in a different table to all the other information. The two tables are linked by ChargeCode which appears in both tblTimesheetEntries and tblChargeCodes.
Have you tried joining the tables on the chargeCode:
SELECT e.[Date],
DATENAME(dw,e.[Date]) AS Day,
SUM(CASE WHEN c.Chargeable = 1 THEN e.Units ELSE 0 END) ChargeableTotal,
SUM(CASE WHEN c.Chargeable = 0 THEN e.Units ELSE 0 END) NotChargeableTotal,
SUM(e.Units) AS TotalUnits
FROM tblTimesheetEntries e
LEFT JOIN tblChargeCodes c
on e.ChargeCode = c.ChargeCode
WHERE e.UserID = 'PJW'
AND e.Date >= '2013-01-01'
GROUP BY e.[Date]
ORDER BY e.[Date] DESC;
